What punctuation does you use for therefore?

Answer 1

If it is used as what is termed an "interrupter," you use a comma. If it is joining two clauses, you use a semicolon before it and a comma after it.

Interrupter: He would, therefore, appreciate a quick response.

Joining clauses: He appreciates quick responses; therefore, I shall endeavour to provide them without delay.

Answer 2

The punctuation used with "therefore" depends on its position relative to the other parts of the sentence or a clause within the sentence.

In some cases, no punctuation is needed:
The sprinter made two false starts and was therefore disqualified.

If it occurs in the middle of an independent clause and separates the subject from the verb, "therefore" is usually set off by commas:
His actions, therefore, were seen as suspicious.

At the beginning of an independent clause, "therefore" is usually followed by a comma:
Therefore, I need to postpone my trip.

When "therefore" introduces an independent clause that follows another independent clause, the two independent clauses should be separated by a semicolon:
I spent the afternoon working in the garden; therefore, I needed to change before dinner.

NOTE: A very common punctuation mistake in this situation is to separate the independent clauses with a comma, creating a comma splice:
I spent the afternoon working in the garden, therefore, I needed to change before dinner.

Answer 3

At the end of a sentence, put comma before. At the beginning of a sentence, put comma after.

Answer 4

For correct punctuation, the word therefore should have a comma or semicolon before and after the word.
